Tired of meeting in subterranean conference rooms? Isn't it boring to get stuck in one plain vanilla room for the whole day? Do you prefer sitting on sofas instead of hard, straight-back chairs? You have this option - plus boardroom, classroom and theater seating - at the mansion and O museum. The mansion is one of the most unique and creative environments in the world. Our expansive footprint includes 12 conference rooms, large meeting galleries, and a host of unique spaces ideal for generating new ideas, motivating teams and getting things done, from 2-300. Our one-of-a-kind environment with creative spaces (and traditional ones too) draws people out of their day-to-day surroundings, and challenges them to solve problems by thinking out of the box.
